You discuss other strategies with your friend, who suggests you could register to be an agent? There's no sign-up charge, you get promo stickers and might attract new customers to the vegetable stand and earn transaction commissions.
What should you do?
You want to grow the vegetable business. An agent, its another business; and lots of work that won't sell vegetables. You aren't convinced.
You like the idea: the bank's stickers will stand out at the market; and the tablets and technology can attract customers. You sign up.
